Many photo-taking scenarios have emotional triggers such as happiness, joy, or in general a good feeling. In this paper we postulate that if a photo was taken to preserve a good feeling, it will most likely trigger a good feeling when re-visiting the photo later on. We present an approach to classify photos and decide automatically whether they have been taken to preserve a good feeling or not....

Rockfall hazard gains popularity nowadays among researchers in different scientific fields, decision-makers and urban planners. The assessment of rockfall requires detection, mapping estimating the maximum travel distance that rock boulders may reach, commonly known as “rockfall runout”. This latter can change significantly under effects triggering factors such soil conditions, chemical, physic...

a b s t r a c tintroduction: craving to methamphetamine is a significant health concern and exposure to methamphetamine cues in laboratory can induce craving. in this study, a task designing procedure for evaluating methamphetamine cue-induced craving in laboratory conditions is examined. methods: first a series of visual cues which could induce craving was identified by 5 discussion sessions b...

The automatic extraction of traffic data from digital images is a challenging task and implies an extensive pre-processing of this data. An important information which simplifies the further extraction of traffic objects is the recognition of active traffic regions. A possible approach is masking of streets using platform attitude and position together with a digital street map (i). But often s...

We study platform owner’s decision to enter the market complementary to its platform with its own rival complement, and the consequences of such an entry on complementors’ innovation behavior. We ask: if a platform owner like Google releases an app for its Android platform, does it keep app developers from innovating in the future? We investigate two mechanisms that suggest entry to stimulate c...

Quantitative identification of physical changes, developments and dynamic position of urban green space is considered as the first step in its planning. By means of the aerial photos taken in 1956, 1974, and 1994 as well as the Quick Bird satellite image captured in 2006, this study has dealt with changes in per capita green space in Khorramabad during these years. First, geometric corrections ...
